RESUMO
OBJECTIVE: It is important to minimize patient discomfort during invasive diagnostic and therapeutic procedures such as bronchoscopy. The aim of this study was to investigate the effect of audiovisual distraction on the tolerability of flexible bronchoscopy (FB). MATERIALS AND METHODS: We conducted a prospective, randomized, controlled trial on patients undergoing FB at a hospital in Zahedan, Iran, in 2015. The patients were equally and randomly divided into a control group and an experimental group. Patients in the control group received standard care during FB While patients in the experimental group selected familiar folk music that was played during the procedure along with the screening of images of nature. The duration of the FB was recorded and cough, dyspnea, choking, nausea and pain were evaluated using a visual analogue scale before and after the procedure. Statistical analysis was carried out using paired and independent t-tests, χ2 -tests and analysis of covariance. RESULTS: Sixty patients met the inclusion criteria and were randomized. The duration of the FB procedure was significantly shorter in the experimental group compared with the control group (mean ± standard deviation 7.87 ± 2.12 min and 10.27 ± 1.72 min, respectively; P < 0.05). Dyspnea, cough and pain were significantly less severe in the experimental group compared with the control group (P < 0.05), but choking and nausea were not significantly different between the two groups (P > 0.1). CONCLUSIONS: Our findings showed that audiovisual distraction had a positive effect on the tolerability of FB. This method has important potential as a simple and practical approach in reducing discomfort during invasive diagnostic and treatment procedures.
